Clock hand for 28BYJ-48 Stepper Motor

This was printed on a polyprinter. The size of the head is slightly oversized since it shrunk a bit in printing, but for me this file produces a snug fit. You may need to adjust it depending on your printer to get a snug fit. Or a little glue. It is designed to fit a 3/8 sized hole.
